[Plugin: WP Super Cache] Is generated the same as served?

Hi, this is what I see at the bottom of my source code…
<!– Dynamic page generated in 2.568 seconds. –>
<!– Cached page generated by WP-Super-Cache on 2012-06-03 01:24:41 –>
<!– Compression = gzip –>

Is this correct as I have noticed on a lot of posts that it should be “served” instead of just generated.
If it should be “served” and I am using PHP to serve my cache files, how should I fix this?

Thank you
